@Alihusejn Mittsu is primarily for 3D graphics. There is a "Sprite" class that can render 2D images in a way similar to most 2D graphics libraries, but Mittsu does not provide a lot of support for that sort of thing, and it likely never will.
If you would like to do 2D graphics in Ruby, I would recommend taking a look at Gosu.
